Floors should be made of
wood or concrete or cov-
ered with ceramic tiles. If
the floor is covered with
synthetic material, then
the relative humidity has
to be at least 30 %.
Electrical fast tran-
sient disturbances /

IEC 61000-4-4
± 2 kV for mains
cables
± 1 kV for input and
output cables
± 2 kV for mains

The quality of the mains
power should correspond
to that of a typical com-
mercial or hospital envi-
ronment.

The quality of the mains
power should correspond
to that of a typical com-
mercial or hospital envi-
ronment. If the user of
the product requires con-
tinued operation despite
interruptions in the power
supply, then it is recom-
mended that the unit be
operated with an uninter-
ruptible power supply or
battery.
Magnetic field of
the supply frequen-
cy (50 / 60 Hz)
IEC 61000-4-8

3 A/m
The magnetic fields gen-
erated at line frequency
should correspond to val-
ues typically found in
commercial or hospital
environments.
